Victoria Beckham says she "needs to work" to prove she can be successful without the Spice Girls or her husband David.
Although the former Spice Girls singer-turned-fashion designer and her soccer player husband have been hugely successful in their respective fields, Victoria admits she suffers from low self-esteem and doubts her abilities.
The 38-year-old star - who was joined in the Spice Girls by Mel B, Emma Bunton, Geri Halliwell and Mel C - told Britain's Elle magazine she wanted to do well in the fashion industry to prove she could make it on her own.
"When I was on stage with the Spice Girls, I thought people were there to see the other four and not me. And when I go out with David and people take pictures, I think, 'They're here to take David's picture.'
"It was never my intention to prove anybody wrong. I wanted to prove to myself that I could do it. I don't have to work, I need to work."
The 38-year-old designer also says nothing has ever been handed to her in her life and she has had to work hard for everything she has achieved in the music and fashion industries.
Victoria said she is determined to instil the same work ethic that she and David, 37 have in their four children - Brooklyn, 13, Romeo, 10, Cruz, seven, and 18-month-old Harper.
"All these people [in fashion], they've not just been given anything. They've worked hard. And I've never been given anything either. But I have a good work ethic. David has an incredible work ethic. I want my kids to have a good work ethic. I believe you can achieve anything if you work hard enough to get it."
